Problems solved by technology

At the same time, this type of intermediate electrode has the disadvantage that additional actions are required to fasten the ring to the insulating body, such as ring crimping
[0004] Another variant of the intermediate electrodes is the clamp, which can be fixed substantially easily on the insulating body in a precise position, however, the use of clamps creates an increased labor expenditure for arranging them, as well as an increased complexity of the intermediate electrodes, resulting in increased costs

Embodiment Construction

[0016] figure 1 Partially showing a 10kV power line protected against lightning using the lightning protection device according to the present invention. In this embodiment, the lightning protection device is manufactured as a cable segment with an insulator forming the insulating body 1 and metal strands serving as rod-shaped electrodes 6 . A metal pipe serving as the second main electrode 3 is provided in the middle of the cable section across the insulating body 1 , and the terminal end of the cable is used as the first main electrode 2 . The ends of the cable strands (ie the rod-shaped electrodes 6 ) are fastened to the wires 4 of the power line by clamps. The second main electrode 3 is fastened to an insulator, which is arranged at the tower 13 of the power line by means of brackets and wires. An electrode 14 forming a spark gap with the second main electrode 3 (the length of the spark gap is 2 cm for a 10 kV power line) is likewise arranged at the tower 13 . A metal s...

Abstract

An apparatus for lightning protection of elements of an electrical equipment or a power line is disclosed. The apparatus comprises an insulating body made of dielectric, at least two main electrodes mechanically coupled with the insulating body, a rod-shaped electrode set inside the insulating body along its axis and electrically connected to one of the main electrodes, and two or more intermediate electrodes set on the insulating body between the main electrodes with mutual displacement along at least a longitudinal axis of the insulating body. The present invention is characterized in that at least part of the intermediate electrodes is made as coil springs being able to be put on the insulating electrode.

Description

technical field [0001] The invention relates to a device for lightning protection of electrical equipment and supporting structures. The invention can be used to protect high voltage devices such as high voltage power lines, insulators and other components, electrical equipment and other structures and equipment requiring lightning protection. Background technique [0002] Patent RU2299508 discloses a shunt device for lightning protection of electrical equipment or power line elements. The device comprises an insulating body made of a solid dielectric, at least two main electrodes mechanically coupled to the insulating body, a rod-shaped electrode disposed inside the insulating body along an axis of the insulating body and electrically connected to one of the main electrodes, and A plurality of intermediate electrodes are disposed on the insulating body between the main electrodes and have a mutual offset at least along the longitudinal axis of the insulating body. [0003...
